cblas_cher2(_:_:_:_:_:_:_:_:_:_:)
Hermitian rank 2 update: adds the product of a scaling factor, vector X, and the conjugate transpose of vector Y to the product of the conjugate of the scaling factor, vector Y, and the conjugate transpose of vector X, and adds the result to matrix A.
Declaration
func cblas_cher2(_ ORDER: CBLAS_ORDER, _ UPLO: CBLAS_UPLO, _ N: __LAPACK_int, _ ALPHA: OpaquePointer, _ X: OpaquePointer?, _ INCX: __LAPACK_int, _ Y: OpaquePointer?, _ INCY: __LAPACK_int, _ A: OpaquePointer?, _ LDA: __LAPACK_int)Parameters
- ORDER:
Specifies row-major (C) or column-major (Fortran) data ordering.
- UPLO:
Specifies whether to use the upper or lower triangle from the matrix. Valid values are
'U'or'L'. - N:
The order of matrix
A. - ALPHA:
The scaling factor
α. - X:
Vector
X. - INCX:
Stride within
X. For example, ifincXis 7, every 7th element is used. - Y:
Vector
Y. - INCY:
Stride within
Y. For example, ifincYis 7, every 7th element is used. - A:
Matrix
A. - LDA:
The leading dimension of matrix
A.
Discussion
Computes A←αX*conjg(Y') + conjg(α)*Y*conjg(X') + A.
